if you had read the twilight series then you will LOVE the movie.
if you have not read it then you will think that it was kind of lame, or the story line seemed thin, only because you did not know the background behind the things that were happening.
so i rate this half and half, if your a die-hard twilight fan and have read the books, then you WILL love the movie, and if you haven't read the books, read it anyway its way better then the movie and you will also enjoy the movies.
